Comparison of Stretching Exercise Methods and Gender to Improve Flexibility in Sports Performers at Mooja Fitness Center

The purpose of this research is for knowing the effect of the stretching method and gender on flexibility. Experimental research method with 2x2 Factorial Design design, which consists of two groups, because the research uses two independent variables with two moderator variables. Frankel et. Al (2013:277). Based on the results of data processing and analysis described in the previous chapter, it is known that the PNF stretching method is more effective than the passive stretching method in increasing muscle and joint flexibility for men and women with a difference in the average stretch score of 1.52. Then on the results of the analysis of differences in muscle and joint flexibility between men and women, it is known that there is a significant difference in the average score of muscle and joint flexibility between men and women where the average score for men is 1.96. In both men and women, there was a significant increase in muscle and joint flexibility between before and after stretching using either the passive method or the PNF method. So the authors can conclude that the results of the study there are significant differences in the average score of muscle and joint flexibility between the PNF method and the passive method. This shows that the PNF stretching method is more effective than the passive stretching method in increasing muscle and joint flexibility in men and women. Utilization of the stretching method can provide real experience for sports players to increase flexibility by using the stretching method, because flexibility is very influential in increasing effectiveness in exercising

ANALISIS KORELASI VOLUME OKSIGEN MAKSIMAL (VO2 MAX) SAAT PEDALING POSISI DUDUK DAN BERDIRI TERHADAP KECEPATAN

Tujuan penelitian ini adalah untuk mengetahui korelasi antara VO2 Max pedaling posisi duduk dan berdiri terhadap kecepatan. Sampel dalam penelitian ini adalah sepuluh atlet junior DKI Jakarta. Metode penelitian yang digunakan adalah deskriptif. Analisis data menggunakan SPSS versi 20. Hasil analisis dan perhitungan data mengungkapkan bahwa VO2 max dan posisi pedaling memiliki hubungan yang signifikan terhadap kecepatan bersepeda, kemudian posisi pedalling berdiri lebih cepat dibandingkan dengan posisi pedaling duduk

Indoor air Quality and Its Effects on Health in Urban Houses of Indonesia: A case study of Surabaya

There is a possibility that the sick building syndrome has already spread widely among the newly constructed apartments in major cities of Indonesia. This study investigates the current conditions of indoor air quality, focusing especially on formaldehyde and TVOC, and their effects on health among occupants in the urban houses located in the city of Surabaya. A total of 471 respondents were interviewed and 82 rooms were measured from September 2017 to January 2018. The results indicated that around 50% of the respondents in the apartments showed some degrees of chemical sensitivity risk. More than 60% of the measured formaldehyde levels in the apartments exceeded the WHO standard, 0.08 ppm. The respondents living in rooms with higher mean formaldehyde values tended to have higher multiple chemical sensitivity risk scores. KEYWORDS: Indoor air quality, Sick building syndrome, QEESI, Formaldehyde, Developing countrie

Keterpelajaran Gerak: Korelasi Keterampilan Psikomotorik dengan Cognitive Function Siswa

This research is a quantitative study with a correlational design that aims to determine the relationship between motor learning and cognitive function in students of public elementary schools in Kuantan Tengah District, Kuantan Singingi Regency, Riau Province. The population of this study was fifth grade students for the 2022/2023 school year, with a population of 627 children spread across 27 public elementary schools. The sampling technique used in this research is random sampling. With this technique, I obtained a sample of 94 students. Methods of data collection using tests and measurements of cognitive function and movement skills Cognitive function uses the Concentration Grid Test (CGT) instrument and movement skills by observing movement learning. The results showed that students' cognitive function was in a good category, and their movement learning was also good. The results of the correlation analysis obtained a correlation coefficient of 0.695 > rtable = 0.396. This shows that there is a significant relationship between movement learning and cognitive function in fifth grade public elementary school students in Kuantan Tengah District for the 2022/2023 academic year. The conclusion that can be drawn from the results of the research is that one student's movement learning is influenced by cognitive function. Students who have good cognitive function tend to have good movement skills

Dorsomorphin treatment and inhibition on phosphorylation of adenosin monophosphate-activated protein kinaseon rats skeletal muscle

This study has been made to determine the effect of dorsomorphin as one of the reagents on adenosine monophosphate-activated protein kinase (AMPK) inhibitor in skeletal muscle. In the experimental procedure, four and eight mg/kg-body weight/day of dorsomorphin were injected every two days for 12 consecutive days (6 times of injection) to Wistar rat. Gastrocnemius muscle immediately harvested from the Wistar rat, continued by protein expression analysis. The analysis also involved regulated mitochondrial biogenesis, including phosphorylation AMPK, SIRT, PGC-1α, VDAC and COX-IV. Results indicated that 8 mg/kg – body weight/day of dorsomorphin decreased protein expression. In the low dosage, dose, such as 4 mg/kg-body weight/day of dorsomorphin, had no impact on decreasing protein expression. Dorsomorphin decreases phosphorylation of AMPK and mitochondrial biomarker, including marker included VDAC and COX-IV on rats skeletal muscle through AMPK-SIRT-PGC-1α pathway
